Striped the threads for the bowl cover

[Fr33zypop]

I knew this would eventually happen as I have been the most gentle with these carbs but last night was the last straw. The threads for the screws for the bowl cover let loose and I wanted to see what options I have are. I am familiar with tapping new threads. The only threads I lost are the one with the little round guides to hold the fuel overflow tubes. I tried and was able to get them tight without those guides so I am wondering it I should look for longer screw? I've only tapped steel so with aluminum I just want to be sure I don't mess it up more. 

 

The last option I have is to get a new pair of 28 keihin and seems like my best option. These old carbs have seen better days..

Depends.. Are you ever going to build a motor or stick with this one?

The current setup meets my needs so probably nothing crazy.

I’d probably just go 28mm PWK then.

Try a longer screw, run a tap in to clean the hole up. Just use lots of oil and go slow, aluminum will plug and bind the tap if you go to fast

Loctight also makes a thread repair epoxy, ive used it and it does work.   Just some options before you buy new

If there is room you can also get a helicoil kit. Amazon  or eBay.  There are the China brands as well for allot cheaper.   Then the threads would be steel and would hold up for the life of the carb
